Life cycle of ASP.Net Web Form Page Request >> Start >> Page Init >> Page Load >> Validation >> PostBack Event Handling >> Page Rendering >> Page Unload Page Request - When the page is requested ASP.Net determines whether the page is to be parsed and compiled or a cached verion of the page is to be sent without running the page. Start - Page propertied REQUEST and RESPONSE are SET, if the page is pastback request then the IsPostBack property is SET and in addition to this UICulture property is also SET. Page Initilization - In this the UniqueID of each property is SET. If the request was postback the data is not yet loaded from the viewstate. Page Load - If it was a postback request then the data gets loaded in the control from the ViewState and control property are set. Validation - If any control validation present, they are performed and IsValid property is SET for each control.

Page Unload - Page is fully rendered and sent to the client(Browser) and is discarded. Page property RESPONSE and REQUEST are unloaded. (More...)
